Figured I"d post the relatively simple solution to installing the double trans cooler lines. after hours of trying everything mostly from the transmission forward I finally just disconnected the lines from the square box that the lines go in to which is part of the set up. they are closer to the transmission hook up side. That enabled me to work from the front of the vehicle and they slid right past everything. Then just re assemble. Make sure to mark the lines first with a sharpie as to which hole in the box they go in to because everything gets a little twisted during install. Took like 20 minutes once I saw the solution staring me in the face. Hopefully this will save someone some trouble because you will not be able to get all of those bends and curves in from the rear.
